Description


A check valve is used to stop the return flow in the high pressure piping. A baffle plate or dart will automatically close when flow returns.


The check valves are made of high strength alloy steel forgings, with unions on both ends to facilitate dismounting the valve in the piping, and have a long operation life in high pressure system. We can provide beeline baffle, top cover baffle and dart type check valves.
